April is spring, a season when grass grows and warblers fly, and spring breezes blow everywhere. This is a good time to enjoy the flowers and scenery, but there is one kind of tree that is very bad at this time, and this kind of tree is the poplar.
In April, the poplars begin to snow, and this snow is loved and hated.
In April, the poplar catkins flying in the sky made many people talk about it, and the poplar catkins and catkins were flying all over the sky, which can be said to have caused public anger, and the reason behind this public anger was because these small things would cause great safety hazards.
However, the problem is that even if these little things flying everywhere have great safety risks, we can still see them in the streets and alleys.
Some people can't help but ask, if these things are a safety hazard, why are the streets and alleys still full of willows and poplars?
«——[Greening heroes to "public enemies of the whole people"·——»
As we all know, the greening of the mainland is very good, and it has always been at the forefront of the world, and we can see willows and poplars everywhere on the green roads beside the road.
Willows and poplars are two of the most common trees in our daily lives, and it can be said that they are the heroes of the mainland's greenery.
In the 70s of the last century, the Beijing area of mainland China was frequently attacked by sandstorms, in order to improve this situation, poplars and willows began to enter people's field of vision, and they were selected as the main force of urban greening.
There is no other reason for this, except that they are drought-tolerant and easy to feed, and their maintenance costs are extremely low, which can be regarded as the nemesis of sandstorms.
In the 70s of the last century, poplars and willows were indeed effective in controlling sandstorms, but as time went on, the problems of poplars and willows gradually became prominent.
Every year in spring, especially in April, poplar catkins and catkins all over the country fly like snowflakes, which brings a lot of inconvenience to people's lives.
Some people even seal the windows of their homes, so it is difficult for Rao to resist the pervasive invasion of poplar catkins and catkins, and in serious cases, they can't even see the road clearly when they go out, and even people's breathing becomes unsmooth when they walk on the road.
For some people with allergies or rhinitis, walking on the road full of poplars and willows in spring is like a torture, but while poplars and catkins are indeed annoying, their role in urban greening cannot be ignored.
They feed oxygen and sequester carbon, absorb harmful substances from the air, and make a significant contribution to the urban environment, but often these details are not seen by ordinary people, and most of the ordinary people focus on the troubles caused by poplar and catkins.
«——【Extremely risky and heavy losses·】——»
The little poplar has a big hidden danger, this is not alarmist, this thing did happen in the Beijing area of the mainland.
Back on May 1, 2017, in a courtyard in Qinghu Town, Fangshan District, Beijing, Ms. Wu cleaned her courtyard as usual in the morning.
After cleaning, Ms. Wu found that the fallen leaves in her yard were piled up, and unfortunately the garbage room was a certain distance from Ms. Wu's house.
Therefore, Ms. Wu looked at the fallen leaves in the courtyard and had a bold idea in her mind, it was better to burn these fallen leaves on fire, and save herself another trip to the garbage room.
However, Ms. Wu did not expect that this convenient move caused a serious trouble.
Coincidentally, something similar happened again one day in May 2019, when a man in Shanghai set fire to a dead tree branch in his home.
The catkins fluttering in the wind also brought the flames to the cold storage next door, which accidentally caused a fire next door.
But catkins are a great contributor to our greening industry, and it is not possible to remove it completely. However, in the face of the catkins problem, people can't do things and dare not care.
Some people also questioned what could be done to reduce the production and harm of catkins since willow trees could not be removed from people's daily lives.
«——【Countermeasures·】——»
For poplars and willows, poplar and catkins are the top priority for their reproduction, so the best way to solve poplar and catkins is to inject poplars and willows with growth regulators such as gibberellic acid or flower bud inhibitors.
This reduces the flower bud differentiation of female poplars, thus reducing the production of poplar catkins. This method can effectively reduce the number of Yang Xu, but such an injection method needs to be done regularly.
In addition to starting from poplars and willow trees, if you want to reduce the production of poplar and catkins in daily life, you can also use a high-pressure water gun to rinse the canopy during the season when poplar and catkins are flying.
Moisten the air and let the poplar fall to the ground. This method can also effectively suppress the amount of poplar catkins in the air.
In addition to the above two methods, changing the tree species is also a feasible method. If conditions permit, some poplars can be gradually replaced with other tree species that are not easy to produce fly floc.
This method can fundamentally solve the problem of poplar catkins, but this method requires long-term planning and implementation, and the cost is slightly higher than the above two methods.
However, compared with the elimination of Yang Xi, the Chinese pay more attention to making the best use of things. Yang Xu is not without benefits.
«——【Turning waste into treasure】——»
Although it is true that poplar catkins have brought a lot of inconvenience to people's lives, they are not without advantages.
Now there are also some businessmen who specialize in collecting poplar catkins in order to recycle them for processing, and the recycled poplar catkins can be made into environmentally friendly materials or fillers.
This can not only reduce the pollution of poplar to the environment, but also realize the recycling of resources. Perhaps between the complete eradication of poplar and the use of waste, waste utilization will be the best choice for things.
Poplar and willow trees as an important force of urban greening, has made a great contribution to our living environment, from a practical point of view, the poplar problem does bring a certain amount of trouble to people's lives, but in fact, this problem is not unsolvable.
We need to take scientific and effective measures to deal with it, reducing the production and harm of poplar catkins is not a far-off thing, we should actively respond to it, and we should also strive to explore alternative uses of poplar catkins.
In this way, we can realize the recycling of resources, and only in this way can we realize the harmonious coexistence of man and nature and create a better future.
